No Drawing.

Specification of Letters Patent. Patented Apr. 30, 1912.

Application filed February 14, 1910. Serial No. 543,869.

To all whom it may concern:

Be it known that I, WILLIAM H. SMITH, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements inProcesses of Making Wood-Stain; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention has for its object to provide an improved shingle or woodstain for exterior use and an improved process for producing the same.

To the above ends, the invention consists of the novel combination ofingredients and steps of manipulation hereinafter described and definedin the claim.

The improved shingle stain, as hitherto made and used, is composed ofcreosote oil, gas drips, benzin, kerosene, boiled linseed oil, paintground in oil and silica. The silica keeps the paint from settling afterall the ingredients are commingled, but, in some instances, will bedispensed with.

The commercial product has been made in the following proportions,to-wit: 800 gallons #2 creosote oil, 100 gallons #2 gas drips, 20gallons benzin, 20 gallons kerosene, 20 gallons boiled linseed oil, 550pounds paint ground in oil and 146 pounds silica F. S. C. A.; but theabove proportions may be varied. The paint ground in oil is to give thedesired color to the stain.

In the improved process of making the above described novel stain, thecreosote oil, gas drips, benzin and kerosene are put in a tank andstirred until thoroughly mixed; are then let stand for about five days,and then all but the settlings are drawn ofi. Then the boiled linseedoil is added and the mixture is again stirred and thoroughly mixed. Thepaint may then be immediately added and stirred into the mixture, inwhich case the silica should be stirred therein at the same time toprevent settling, or the paint may be shipped with the ingredients ofthe stain minus the paint and the paint added at the place where it isintended for use, in which case the silica be dispensed with; orotherwise stated, the silica should be added when the stain colored withthe paint is not to be used for a considerable time after theingredients have been mixed together.

What I claim is:

The process of making wood stain which consists first, in mixingtogether creosote oil, gas drips, benzin and kerosene, and allowing thesame to stand and settle, then separating the settlings from the clearliquid and subsequently mixing therewith boiled linseed oil, paintground in oil and silica.

In testimony whereof I aflix my signature in presence of two witnesses:

\VILLIAM H. SMITH.
